The attached PDF contains a number of links to materials on the web which contain real information about the Q900. Many pages I have seen are just quoting ad material. None of those are listed here. Unfortunately, the best videos are not in English. We cold use a good Chinese ham who actually knows English.

You should be able to click on the links to go directly to the site. The links are live.

If you find similar (or better) sites, let us know and the list will grow.
